An instrument delivery device to couple to a vascular access device. The instrument delivery device may include a housing, which may include a distal connector, a proximal connector, and a lumen extending through the distal connector and the proximal connector. The instrument delivery device may include a vascular access instrument, which may include a distal end and a proximal end. The vascular access instrument may be disposed within the lumen of the housing in a coiled position. The vascular access instrument may be configured to move from the coiled position to an uncoiled position and advance through the distal connector. The vascular access instrument may extend through the vascular access device into vasculature of a patient.

Vascular instrument delivery device and related systems and methods

A catheter system may include a catheter adapter, which may include a distal end and a proximal end. The catheter system may include a catheter, which may include a distal end, a proximal end, a catheter lumen extending through the distal end of the catheter and the proximal end of the catheter, and an inner surface forming the catheter lumen. The catheter may extend distally from the distal end of the catheter adapter. The distal end of the catheter may include one or more holes. The distal end of the catheter may include one or more channels. The holes and/or the channels may facilitate visualization of blood flashback indicating the catheter is disposed within a vein of a patient.

Confirmation of catheter placement within a vein

An instrument advancement device may include a housing and an extension tube extending through the housing. A wedge may be disposed within the housing. The wedge may include an arc-shaped channel. A pair of opposing pinch members configured to pinch the extension tube may be disposed within the housing and configured to move along the extension tube. An instrument may extend through the arc-shaped channel. A first end of the instrument may be fixed. In response to moving the housing distally along the extension tube, the pair of opposing pinch members may push the wedge distally. In response to movement of the wedge distally a first distance, a second end of the instrument may be configured to advance distally a second distance. A support element or compressible element may be disposed within a lumen of the extension tube to support the instrument.

Instrument advancement device having an anti-buckling feature

A delivery device to deliver a guidewire through an intravenous catheter assembly may include a housing, which may include a distal end, a proximal end, and a slot. The delivery device may include a guidewire, which may include a proximal end and a distal end. The delivery device may include a guidewire hub disposed within the housing. The guidewire may be secured to the guidewire hub, and the guidewire hub may be configured to move along the slot to advance the guidewire in a distal direction. The distal end of the guidewire may include a fluid permeable structure. For example, the fluid permeable structure may include an elongated core and a coil extending around the elongated core. In some embodiments, a space between the elongated core and the coil may be configured to receive blood in response to the guidewire being inserted into the vasculature.

Vascular access instrument having a fluid permeable structure, and related devices and methods

A catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, and a lumen extending through the distal end and the proximal end. The catheter assembly may include a catheter secured within the catheter adapter and extending from the distal end of the catheter adapter. The catheter adapter may be configured to move between a first position and a second position. In response to the catheter adapter moving from the first position to the second position, an angle of the catheter adapter with respect to an insertion surface may be configured to increase, which may improve patency of the catheter assembly and alignment of a fluid path of the catheter assembly with vasculature of a patient.

Catheter assembly with angle changing and related methods

An IV device assembly may include a lumen forming a fluidic channel within the IV device assembly. The lumen may be fluidically coupled to a vascular access device (VAD) coupler via a funnel coupler, and an IV device assembly coupler at a proximal end of the lumen. The IV device assembly may also include one or more of the following: a collapsible sleeve formed coaxially around a first portion of the lumen and mechanically coupled to the funnel coupler, a probe formed along a second portion of the lumen within the collapsible sleeve and into the VAD coupler, a translation handle that translates the probe out of a distal end of the VAD coupler, and a fixed grip formed around the lumen to maintain a position of the IV device assembly relative to the translation handle.

Vascular access device assembly facilitating single-handed probe advancement with a support member

An IV catheter device can include or being configured to employ a probe assembly having an integrated fluid flushing mechanism. The probe assembly can be configured in a variety of ways to cause flushing fluid to be injected through a fluid permeable structure of the probe as the probe is advanced distally from a catheter. In this way, the fluid permeable structure can be kept clear of any occlusion that may otherwise form. With the probe extending distally from the catheter, a blood sample may be collected.

Intravenous catheter device having a probe assembly with an integrated fluid flushing mechanism

A cannula capture mechanism is described herein. The capture mechanism may include an inner housing, outer housing, and a cannula. The outer housing may be configured to move between a compressed and a decompressed state. An outer surface of the inner housing may include one or more interlock components. When the cannula is exposed from a distal end of the inner housing, the one or more interlock components may interact with one or more interlock surfaces formed in another surface of the catheter device. When the cannula is retracted proximally within the inner housing, the inner housing may contract radially inward causing the one or more interlock components to be separated from the one or more interlock surfaces and the outer housing to move to the decompressed state and extend distally over a distal portion of the inner housing.

Cannula capture mechanism

A catheter adapter may include a distal end, a proximal end, a lumen extending between the distal end and the proximal end, and a side port. A central axis of a fluid path extending through the side port may be disposed at an angle with respect to a longitudinal axis of the catheter adapter. The angle may be less than 45°. Additionally or alternatively to the angle being less than 45°, the catheter adapter may include a wedge and/or an insert configured to facilitate instrument delivery to the catheter assembly via the side port.

Systems and methods of facilitating instrument delivery to a catheter assembly

An extension set may include a tube having an outer surface. An instrument, such as a tubing or a probe, may be disposed within the tube and may include a proximal end and a distal end. A translation handle may be coupled to the outer surface of the tube and may move along the outer surface between a proximal position and a distal position to translate the distal end of the instrument between a retracted position and an advanced position. In the advanced position, the distal end of the instrument may extend beyond the distal end of the tube and into a catheter assembly and/or vasculature of a patient.

Extension set and related systems and methods

A catheter system may include a catheter adapter and a wing extending outwardly from the catheter adapter. The wing may include a groove or slot. The catheter system may include a needle hub and a paddle extending outwardly from the needle hub. The paddle may include an extension disposed within the groove or the slot to reduce axial movement between the catheter adapter and the needle hub, which may be advantageous during insertion of the catheter system into a patient. The extension may be removable from the groove or the slot to allow axial movement between the catheter adapter and the needle hub during removal of the needle hub from the catheter adapter, for example. The paddle and/or the wing may include a shape to reduce axial movement between the catheter adapter and the needle hub, which may also be advantageous during insertion of the catheter system.

Providing resistance to separation of a catheter adapter and a needle hub

A catheter assembly and/or an introducer may include one or more features configured to guide a probe and/or a catheter distally through a septum. The catheter assembly may include a catheter adapter and the septum. The catheter adapter may include a distal end, a proximal end, and a lumen extending therebetween. In some embodiments, the septum may be disposed within the lumen. The septum may include a proximal surface that is tapered inwardly in a distal direction such that the proximal surface of the septum is configured to guide the probe and/or the catheter distally through the septum. The catheter assembly may be configured to receive an introducer, which may include an introducer element. A proximal end of the introducer element may include another proximal surface that is tapered inwardly in the distal direction such that the other proximal surface is configured to guide the probe or the catheter distally through the septum.

Systems and methods to improve instrument guidance within an intravenous catheter assembly

Inserts can be formed with elution characteristics to cause the inserts to elute an antimicrobial agent when subject to a fluid within a medical device. An insert can be formed with a desired geometry to allow the insert to be compression fit within a medical device to prevent the insert from moving or becoming dislodged once inserted into the medical device. The material may also be hygroscopic so that the insert swells when subject to a fluid thereby enhancing the compression fit of the device within the medical device. In some cases, the material can be reinforced using an internal structure. Inserts can be formed in many ways including by casting, thermoforming, or extrusion. In some cases, the inserts can be formed using a peel-away sleeve or material. The peel-away sleeves can be formed of a non-sticky material which facilitates removal of the inserts once the inserts have cured.

Antimicrobial inserts for medical devices

A blood collection system may include a needle assembly, which may include a needle configured to receive an evacuated blood collection tube. The blood collection system may include a tubing, which may include a distal end and a proximal end. The proximal end may be coupled to the needle assembly. The tubing may include a first flow channel and a second flow channel. The first flow channel may be configured to collapse at a lower pressure differential than the second flow channel.

Blood collection system with automatic pressure management and related methods

A delivery device to deliver a tubular instrument into a catheter extending distally from a catheter adapter. The delivery device may include a housing configured to couple to the catheter adapter. The delivery device may include a tubular instrument configured to insert through the catheter. The tubular instrument may include a distal end, a proximal end, and a lumen extending between the distal end and the proximal end. The distal end may include a distal tip, which may be closed. The proximal end may be secured within the housing. The tubular instrument may be configured to advance distally with respect to the housing. A portion of the distal end proximate the distal tip may include a first material and maybe stiffer than the distal tip, which may include a second material. A durometer of the first material may be greater than a durometer of the second material.
